AO3-6653 Fix missing space in actions/labeler config (otwcode#4700)

* AO3-6653 Use an array even for single glob

* AO3-6653 Try removing the problematic labels temporarily

* AO3-6653 Let's try labels without colons

* AO3-6653 It's not the colon so it must be any-glob-to-all-files

* AO3-6653 Restore the quotation marks for Scope Tests Only glob

* AO3-6653 Temporarily remove Scope i18n Only

* AO3-6653 Restore colon for Scope: Tests Only label

* AO3-6653 Restore Scope: i18n Only, using single quotes for glob

* AO3-6653 Move Scope: i18n Only to bottom

* AO3-6653 ...add missing space
